9 hour layover in sharjah

Hi, I am flying to malaysia via Air Arabia and i have a 9 hour layover at sharjah airport from 6 am to 3 pm. I was wondering if it is possible to see a little bit of dubai during this timeframe. I'm aware i wouldn't have much time, but even if i could squeeze out 3-4 hours in dubai it would be worth it for me, I just want a nice view of the burj khalifa and something to eat. I do not have any checked backs either. I saw that a taxi could take 50 min to an hour to reach dubai but i also saw something about a shuttle bus service for Air arabia passengers that takes you to dubai. Thoughts/advice?
